Truly wireless earphones are all about balance, and the C8s from Pioneer are on the money. Sound is excellent with deep bass from powerful drivers and AAC codec delivered via Bluetooth wireless technology. Battery life is strong: charge up for three hours of listening and the carry-case will charge the earphones twice before needing to charge the case. Voice access to smartphone assistants, hands-free calling, and music control come via buttons designed for easy convenience. The C8 works with an Android app that reads out notifications, a feature unique to Pioneer. But the difference is in the detail: unique L/R shapes, body-agnostic charging ports, textured silicon sleeves for grip, and LED battery indicator on the case. Light, practical, immersive, the C8 truly wireless has freedom you need.
